How Does Charging an AGM Battery Differ from Charging Standard Lead-Acid Batteries?
Charging an AGM battery differs from charging standard lead-acid batteries in several key ways. AGM batteries, or Absorbent Glass Mat batteries, have specific charging requirements due to their construction. Unlike standard lead-acid batteries, AGM batteries can sustain deeper discharges and have lower internal resistance.
AGM batteries require a higher voltage during the charging process. A typical charging voltage for AGM batteries is around 14.4 to 14.7 volts, while standard lead-acid batteries usually require a voltage of about 13.8 to 14.2 volts. This difference ensures faster charging and helps maintain the AGM battery’s lifespan.
Additionally, the charging rate of AGM batteries often requires a smart charger or a compatible charging system. These chargers can adjust the voltage and current automatically. This feature prevents overcharging and minimizes heat buildup, which can damage AGM batteries.
Lastly, AGM batteries do not vent gases like traditional lead-acid batteries during charging. This characteristic allows AGM batteries to be placed in tighter spaces without venting hazards.
